- Full or Partial Refund, if the item is not as described
- Full Refund if you don't receive your order
Description
The HA17451 is a dual-channel switching regulator controller IC. Each channel
contains the basic circuits for controlling a PWM-type switching-regulator
power supply. Both channels are integrated onto the same chip. Both channels
can be completely synchronized, using the same oscillator output waveform.
Each channel can provide output voltages for step-up, step-down, inverting,
and other converter topologies.
These controllers operate at voltages from 3.3 V to 40 V, making them suitable
for a wide range of applications. They are ideal for chopper-type DC/DC
converters. They are similar to the TL1451, but note that the HA17451A differs
from the TL1451A.
Features
• Low dropout voltage of on-chip 2.5V voltage reference: Vdrop = 0.2 V (typ)
• Operates throughout wide supply voltagerange: 3.3 V to 40 V
• Large maximum output current: 50 mA (max)
• Undervoltage lockout circuit
High threshold voltage: 3.15 V (typ)
Low threshold voltage: 2.98 V (typ)
• Low current drain: 1.5 mA (typ)
• Operates at wide range of oscillator frequencies: fOSC= 1 kHz to 300 kHz
• Dead time adjustable through full duty cycle range
• Surface-mount package (SOP16) for saving space (HA17451AFP)
Functions
• Low-dropout 2.5V voltage reference
• Undervoltage lockout
• Triangle-wave oscillator
• Adjustable dead-time control
• Error amplifier
• Output driver (open-collector transistor type)
• PWM comparator
